Quite right Stevie. Rather sloppy speaking. As far as I know, neither Blandiver nor Penn Jillette have any training as scientists so perhaps they can be excused. You, on the other hand, have recently said "I have a scientific background" so you should know better.(Although a while ago you said "I'm not speaking as a "scientist"". Confusing.)

I'm a bit busy at the moment. I'll get back to you.
